Workflow routing options radio buttons

So we have migrated our workflows from 9.1 to 11.0.  We have got most things to work.

One issue, If there is a workflow task that goes to multiple users (all users required to complete) at the same time and there is a routing choice of radio buttons.  The task displays with nothing preselected, which is how it should.  So that user makes a selection and completes the task.  But when the next user looks at the task, the routing radio button is preselected with the previous users selection.  I would expect each user to view the task and the routing options are not selected.  What is going on?

This works correctly in 9.1, with the blank radio buttons for each user.
